A perfusionist in front of a heart–lung machine (upper right) early in a coronary artery bypass surgery. A cardiovascular perfusionist, clinical perfusionist or perfusiologist, and occasionally a cardiopulmonary bypass doctor [1] [2] or clinical perfusion scientist, [3] is a healthcare professional who operates the cardiopulmonary bypass machine (heart–lung machine) during cardiac surgery ...
Perfusion is the passage of fluid through the circulatory system or lymphatic system to an organ or a tissue, [1] usually referring to the delivery of blood to a capillary bed in tissue. Perfusion may also refer to fixation via perfusion, used in histological studies.
The harvesting of both two thoracic arteries is a risk factor because it significantly impairs the perfusion of blood through the sternum. [38] Pneumonia can also occur. [42] Complications in the gastrointestinal tract have been described and are most commonly due to medications administered during the operation. [39]
Perfusion is the passage of fluid through the lymphatic system or blood vessels to an organ or a tissue. [1] The practice of perfusion scanning is the process by which this perfusion can be observed, recorded and quantified. The term perfusion scanning encompasses a wide range of medical imaging modalities. [2]
Ventilation–perfusion coupling is the relationship between ventilation and perfusion in the respiratory and cardiovascular systems. [1] Ventilation is the movement of air in and out of the lungs during breathing. [2] Perfusion is the process of pulmonary blood circulation, which reoxygenates blood, allowing it to transport oxygen to body tissues.
Machine perfusion (MP) is an artificial perfusion technique often used for organ preservation to help facilitate organ transplantation.MP works by continuously pumping a specialized solution through donor organs, mimicking the body's natural blood flow while actively controlling temperature, oxygen levels, chemical composition, and mechanical stress within the organ.
Respiratory therapists are able to fulfill the role of perfusionist with appropriate training. The perfusionist is a highly trained member of the cardiothoracic surgical team (often time an RT with extra training) which consists of cardiac surgeons , anesthesiologists , physician assistants , surgical technicians , other respiratory therapists ...
Coronary Vasculature. Coronary perfusion pressure (CPP) refers to the pressure gradient that drives coronary blood pressure.The heart's function is to perfuse blood to the body; however, the heart's own myocardium (heart muscle) must, itself, be supplied for its own muscle function.
